And if you're looking to catch some rays away from the crowds, one Welsh beach has just been named the best hidden coastal gem in the country. Trearddur Bay, located just south of Holyhead on the Isle of Anglesey, has been named the UK's best lesser-known beach destination. The new study - conducted by Insure4Boats - analysed over 250 UK coastal towns using Met Office data, Instagram popularity, and local attractions, and found the North Wales resort to be a standout spot for sun-seekers and water sport lovers alike. Described as 'prestigious' with 'crystal clear waters,' Trearddur Bay scored high across the board, with a perfect 10 on Instagram, high sunshine and low rainfall ratings. Whether you're keen on kayaking, paddleboarding, or simply taking in the panoramic sea views, the bay is hailed as a playground for outdoor enthusiasts. There's plenty to explore beyond the beach itself: rock pools, scenic walking trails, and an assortment of cafés and restaurants - including the beachfront Sea Shanty Café - can keep visitors busy well into the evening. Located right next to the beach, the Sea Shanty Café serves up plenty of traditional seaside fare, including cod and scallops, along with menu items with a twist, such as moules frites and Thai fish cakes.

Fantastic beaches, walks, National Trust and pubs.' Another user, a Trearddur Bay resident, said: 'I live in Trearddur Bay, have been here for about 15 years. I feel lucky to live in such a safe and clean area, and this is the case all year round. 'The beach is very clean and is manned by wardens in the summer, there is a life boat station here also. The village is not bustling with lots of night life, however there are places to go and importantly for you children are welcome there.' Finally, a third wrote: 'Lovely clean but quiet area. Great for walks, cycling, young children with 2 or 3 very good places to eat. Sea shanty, black seal and trearrdur hotel. Very impressed and will be back again very soon.'
